LM2765
Switched Capacitor Voltage Converter
General Description
The LM2765 CMOS charge-pump voltage converter oper-
ates as a voltage doubler for an input voltage in the range of
+1.8V to +5.5V. Two low cost capacitors and a diode are
used in this circuit to provide up to 20 mA of output current.
The LM2765 operates at 50 kHz switching frequency to re-
duce output resistance and voltage ripple. With an operating
current of only 130 A (operating efficiency greater than 90%
with most loads) and 0.1A typical shutdown current, the
LM2765 provides ideal performance for battery powered
systems. The device is manufactured in a SOT-23-6 pack-
age.
